Hands-On Object-Oriented Programming with Kotlin

Using the super keyword

So far, all classes were inherited using a primary constructor. If the Student class doesn't have a primary constructor but a secondary constructor instead, the secondary constructor can be preceded by the super keyword:

class Student: Person {    constructor(fName: String,lName: String, age: Int, id: String) : super(fName,lName,age, id)    fun aboutEducation(){        println("I am a student of Computer Science.")    }    fun attendLectures() {        println("I am studding Introduction to Kotlin lecture.")    }}

The super keyword will call the constructor of the super or parent class to initialize the properties of the parent class.
